SPECFEGATION forming part of Letters Patent No. 600,505, dated March 15, 1898.

. Application tied ouate' i5, i896.L

T0 all whom, it nto/y concern:

Beit known that I, ALDEN L. BAILEY, a citizen of the United States, residing at St. Johnsbury, in the county of Caledonia and State of Vermont, have invented certain new and useful Improvements in Hose-Couplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to couplings having duplicate interlocking sections, the objects of the invention being to provide, iirst, a hosecoupling the sections of which may be quickly connected; second,one which does not require the frequent removal of gaskets to take up the wear, and, third, to provide a coupling which may be separated under a longitudinal strain.

The invention consists in a coupling composed of duplicate sections and of the novel construction to be fully set forth in the following speciiication and claims and clearly illustrated in the accompanying drawings, forming a part of the same, of which- Figure l is an end elevation of one of the duplicate sections of my improved coupling complete, Fig. 2 being a broken side elevation of the same. Fig. ,3 is an end elevation showing a modiiied form of one section of the coupling from which the retaining-sleeve is removed. Fig. 4 is a side elevation of the modification illustrated in Fig. 3. Fig. 5 is an end elevation of one of the retainingsleeves, and Fig. 6 is a vertical section of the same.

Similar reference-letters denote corresponding parts in all the views.

One section of my improved coupling is the exact counterpart of the other.

A represents either section of the improved posite sides from the outer end. These tongues are made slightly tapering on their edges, as at o, and on their inner surface, as at b', the latter being tapered to tit the tapered curved surface of a reduced portion a of either section A, and when united the tongues B of one section ll the spaces between those of the other section.

Each section A has an externally-threaded portion c', to which is threaded a sleeve C.

Serial No. 6Q9 .004. (No model.)

Each tongue B has a beveled lateral projection for engaging with the sleeves, as hereinafter explained, and these beveled projections may be formed integral with the tongues, as seen in Figs. 3 and Il, at h2, or they may be formed at one end of a yielding plate fitted into a recess formed for the purpose in the inner surface of the tongues, this form being illustrated in Figs. l and 2 at b3. The sleeves C have in their outer ends an annular recess c, provided on opposite sides of its outer edge with an internal flange c', and to unite the sections A of my improved coupling the tongues B of either section, provided with a lateral projection b2 or b3, enter the recess c of either sleeve C, and by slightly turning the latter the projections b2 or b3 are brought to a position behind the flanges c' of said sleeves, and as the sleeves revolve only upon the threaded portion u. of the sections A the rotation of said sleeves brings the gaskets D of the coupleresections into close contact by pulling against said laterally-inclining projections of the said tongues.

In the drawings the laterally-inclining proj ections are shown to be beveled on both sides, and this is essential for the spring-actuated projections b3, which must be beveled on their back sides, as at o, and the inner sides of the iianges c must be likewise beveled, as at c2, so that by applying force in a horizontal direction to separate the sections A the free ends of the spring plates or arms b5, upon which the projections b3 are formed, will yield inward and permit the said projections to be crowded downward and under the said flanges of the sleeves C, thus disengaging one section from the other by force, as Would be sometimes necessary if my improved couplings should be applied to railway-hose, any given strain at which the coupling may be required to separate being readily determined or regulated by the inclination or particular degree of angle given to the surfaces b4 and c2, respectively, of the projections b3 and flanges c.

It is obvious that the threaded sleeves C when turned to the proper place upon the sections A must be provided with some suitable stop, a convenient means of providing this being shown in the drawings. The sleeves C are each provided with a slight groove c3, formed in the shoulder or offset,which results lOO from the enlargement or recess c, and this groove receives a portion of the head of a screw E, threaded to each section, as shown.

Having described my1 invention, what I claim is- 1. In ahose-coupling composed of duplicate sections, a pair of tapering tongues arranged at opposite sides of their adjacent ends each tongue being provided at its end With a laterally-inclining proj ection,an external threaded portion located back of the tongues on each section, and a threaded sleeve fitting the threaded portion of each section having an internal annular recess adapted to receive the laterall'y-inclining projection of said tongues, substantially for the purpose set forth.

2. In ahose-coupling composed of duplicate sections, a pair of tapering tongues arra-nged at opposite sides of their adjacent ends the tongues of each section lilling the space between those of the other When united, a laterally-inclining projection at the end of eachv tongue, an external threaded portion located back of the tongues on each section, and a threaded sleeve fitting the threaded portion of each section having an internal annular recess adapted to receive the laterally-inclining projection of said tongues, substantially for the purpose set forth.

3. A hose-coupling composed of duplicate sections having a pair of tapering tongues arranged at opposite sides of their 'adjacent ends, having each an internal longitudinal recess, a yielding bar fitting each ot said recesses and secured at one end to each section and having a laterally-inclining projection at its free end, a sleeve threaded to each section having an internal annular recess adapted to receive the spring-actuated laterally-inclining projections of said tongues, substantially for the purpose set forth.

4. A hose-coupling composed of duplicate sections having a pair of tapering tongues arranged at opposite sides of their adjacent ends, the tongues of each section being provided With an internal longitudinal recess and being adapted to close the space between the tongues of the other when united, a springactuated bar iitting the recess in each tongue provided at its free end With a laterally-in clining projection, a sleeve threaded to each section having an internal annular recess adapted to receive the laterally-inclining projections of said bars and to lock said sections together by a slight rotativev movement.

5. A hose-coupling composed of duplicate sections having a pair of tongues arranged at opposite sides of their adjacent ends the tongues of each section filling the space between those of the other When united, alateral spring-actuated projection secured to each tongue and tapered both sides, and a sleeve threaded to each section having an internal annular recess adapted to receive the springactuated projection of said tongues and to lock said sections together by a slight rotative movement.

In testimony whereof I affix my signature in presence of two Witnesses.
